On one hand, I completely understand wanting to get rid of competition that is doing vaccines at rates you just can't match. On the other hand, I can't see it being a good idea to continue with the effort to shut these places down. My two cents:
1. Based off of the sentiments of veterinarians I have worked with, they don't necessarily want to provide services to those who come in and either a. refuse to pay over a certain amount, regardless of income b. honestly cannot afford good care (routine or emergency). While they certainly want to provide that quality care to these animals, they cringe whenever they hear "Oh, and I don't have more than $50 for this" or "Doctor, we're stopping at $100, okay?" This is how veterinary medicine becomes a charity, and how good doctors end up volunteering in their own businesses. If you don't offer freebies, you're a horrible person. These low cost clinics pull those clients with financial troubles or those who just don't want to pay, and the clients who can pay/willing to pay will remain. These clients can't go to a low cost emergency clinic, though, so they'd still have to go to the 'normal' clinic anyways. I can't see it being a HUGE loss, although I can understand when some clinics are pinching pennies that they might feel that loss a bit more.
2. I guess I can see why these places should be more regulated. I've met a few clients who went to Tractor Supply or Petsmart or even just to the local shelter for cheap vaccines, and came to us the next day asking why their dog was covered in hives. "Well, your dog had a vaccine reaction. Why didn't you call the vet that gave the injection?" "They're not there anymore, and they never told me this could happen. I called and they told me to see another vet." I'm not sure if government involvement would solve those particular issues that I've experience such as: Not warning clients about potential reactions, not giving clients proper/good instructions for meds, not emphasizing the importance of keeping your receipt potentially for the life of the dog so you can provide a history in the case of an emergency, etc. You can argue that these clinics don't necessarily serve to educate, but to me, those are basic points that the doctor/tech/assistant/whoever at these low cost clinics needs to cover. Hearing "I don't know what vaccines my dog got, we just took him to the local pet supply store and they did some stuff" occurs far too often. Clients should take charge and know these things, but a lot don't realize that they should, in fact, know these things. Maybe government involvement would force these low cost clinics to be more liable? Maybe not.
3. This could be because I'm still trying to butt my head into the field, but what exactly is meant when the article says vet med is already a highly regulated industry? Last I heard, we were enjoying the spoils of ELDU. And enjoying the work of volunteers/shadows, who can be in the exam room with a doctor without worrying about HIPAA-esque laws. I know there are still confidentiality measures, but not to the same extent.
